The specs for a 1929/30 iron heads are 60 ft lbs. Most PA guys use 65 ft lbs. We are told:

* use a circular pattern from center out

* Clean threads and use new bolts

* Use a special non sieze compound on the threads

* Tighten when engine cold – do not tighten when hot

* Run engine and let cool down then tighten again.

I am not an expert on this. Others may have some suggetions.

Correct head gasket very inportant.
